I have to say, I'm impressed with the engineering that went into the design of this cooler.

Yep....took a lot of engineering to look at the Noctua NH-L12S and think "maybe it would do better with another fin array placed under the bottom fan with 2 extra heatpipes".... Because, that's exactly what it looks like they did.

Wait... is there no any solid connection between bottom and top metal heatsink??
I don't think top heatsink conducts temperature from bottom heatsink. Its just seem to be heated up by hot air from bottom.
